Best review ever! Really appreciate the effort you and the guys must have gone to for this! Clearly proves that 3-way is good if a little expensive, but 4-way is just stupid for anything except PC Mark really. What a well made board though! Even if that stupid chipset heatsink is a massive gimmick , it's nothing short of awesome! Well done OC3D!

Fantastic, amazing, fabulous, unbelievable, jaw dropping, there is not enough words in the dictionary that would describe this review and videos I enjoyed every minute of it and to be honest I read it twice actually it was better than watching AVATAR in 3d in the cinema, I’m a very critical person by nature but OC3D you deserve a 5 star for this one as for the videos I watched them in 1080p on my 40’’ Samsung to enjoy every single detail there is and it is truly amazing stuff guys and the watermark oh... just lovely truly professional , If it was up to me I'll put this review on the BBC it would definitely be better than watching click, to be honest there is nothing ells I can say to show my appreciation to you guys for giving me a two hour journey of pure enjoyment. I truly love you guys.

Fantastic looking board. I don't think there will be too many wanting to shill out £450 for this though with the new round of CPUs on the horizon.

4xsli is a joke. How gutted would you be if you bought the board for that reason only to get the results you have shown.

Mate with crazy overclockers who just want a few extra frames and seek to have the highest benchmark scores on the planet the term (money is no object) comes in to mind this is what this board is designed for not for a normal enthusiast which takes price in to consideration believe me if there was 5 way sli these people will go for it it’s the same thing as the car racing culture they just add on more gear to their cars to make them a bit faster and the cost is tremendous and you need to bear in mind that this mad drive to be faster and faster is what makes the computer industry evolve continuously and it has become the fastest growing market in the world.

Count me in the lot that has more money than sense. Well significantly less money now that the ud9 lives in my case.

I am not rich, by any means. Let me point one thing out though. I do multimedia production work, and use some proprietary PCIe cards in that work. The cards MUST follow consecutive slot orders. So that made the ud9 one of only 3 options for my needs. The EVGA lacked the sata3 and a few features. The ASUS SC has been plagued with problems. So that only left the ud9. Well to be fair there was a small assortment of high end server boards also, but none exactly fit the bill.

ALSO, Gigabyte does make the promise that they will "custom engineer" BIOS features for ud9 users. This is critical for my needs. As my software/hardware matures, I am constantly running into dma/irq issues with mobo's/os's. If Gigabyte makes good on their promise and expedites BIOS implementations even ONE day ahead of the competition. The board has payed for itself.

Not to brag or tout my other hardware, but the proprietary PCI cards I use run about $15k for 3, so the premium for the ud9 was really not that big of a deal (in the bigger picture).

Now for the icing on the cake. I was previously running these cards in a MAC

Apple was forcing me to buy a new $7k computer every 2 years or so, just to keep up. So now that I moved over to a Win platform, the performance is through the roof....and I have under $4k into a system that utterly DEMOLISHES the MacPro in BOTH cost and performance.

I think the ud9 is actually a bargain, considering what it does. If there was ONE single competing product on the market...I would call it as you have.....but there is not.

I don't regret my purchase one bit. I am not just talking artificial benches....I am talking REAL WORLD performance. 24/7
